A client terminal displays on a graphical interface a first indicator of a price associated with a lowest traded price of a tradable object during a predetermined period of time, a second indicator of a price associated with a highest traded price of the tradable object during the predetermined period of time, along with at least one quantity indicator associated with at least one order to buy/order the tradable object. The first indicator, the second indicator, and the at least one quantity indicator are displayed in relation to a static axis of price, and the client terminal dynamically updates the first and second indicator to new lowest and highest traded prices based on market updates received from an exchange.
